DEVICE FOR STRETCHING THE STRINGS OF MUSICAL INSTRUMENTS.

To all whom it may concern:

Be it known that I, J OHANNES WILHnLMUs VAN I-IOUTEN, a subj ect of the Queen of N etherlands, and resident of Prinsengracht 1051, Amsterdam, Netherlands, have invented certain new and useful Improvements in Devices for Stretching the Strings of Musical Instrubut it could only be accomplished in this way very imperfectly.

The present invention relates to a device by means of which this stretching can be accomplished in an easier and more perfect manner.

This device consists essentially of asmall roller attached to a handle, by means of which the strings can be held up. The roller is led along the string, the latter being thereby pulled out at the same time.

In the accompanying drawings Figure 1 shows a front view, and Fig. 2 a side view of the new device. Fig. 8 shows how the device is used.

The handle a fashioned in anysuitable manner is provided at or near the bottom Specification of Letters Patent.

Application filed February 4, 1907.

Patented. March 10, 1908.

Serial No. 355,656.

with a laterally projecting roller made from any material suitable for the purpose. roller 1) should be made as small as possible so that it can be easily brought underneath the strings. For this reason it is desirable if the roller is ournaled on a pin which is only fixed at one side as shown in the drawing. The roller is provided with a groove in the same manner as a pulley in order that the string may not slip off. The handle may be made rough in order that it may be firmly gripped by the thumb and linger.

What I claim as my invention and desire to secure by Letters Patent is In a device for stretching the strings ofmusical instruments, in combination, a small handle of suitable form, a p111 fixed with one end on the said handle, a small roller journaled on the said pin, and a groove of semicircular cross-section on the periphery of the said roller, said grooved roller being adapted to be inserted under the strings of a musical instrument, substantially as shown and for the purpose set forth.

In testimony whereof I have hereunto signed my name this 16th day of January, 1907, in the presence of two subscribing Witnesses.
